Subject: [PATCH] Fix 'g++.dg/cpp26/static_assert1.C' for '-fno-exceptions'
 configurations

This test case, added in recent commit 6ce952188ab39e303e4f63e474b5cba83b5b12fd
"c++: Implement C++26 P2741R3 - user-generated static_assert messages [PR110348]",
expectedly runs into 'UNSUPPORTED: [...]: exception handling disabled', but
along the way also FAILs a few tests:

Use an explicit '-fexceptions' to turn this front end test case all-PASS.
